Hitachi VFD EtherCAT Parameter Settings
To set up the Hitachi VFD to be commanded by EtherCAT you will need to modify 2 parameters:
|
Parameter |
Description | Default Value | Desired Value |
|
AA101 |
Main Speed Source_M | 1 (Term.[Ai1]) | 9 (Option-1) |
| AA111 | Run-cmd. Source_M1 | 0 (Term.[FW]/[RV]) | 4 (Option-1) |
If there is a delayed safety relay (knob or switches on the front of the safety relay), you will need to set up the following:
(BOM Example: 
)
- CA-03: 31 (Sets S3 input to fast stop)
- CA-23: 1 (Sets S3 input to Normally Closed)
- AC-126: 4 (Or to your fast stop deceleration time - match standard decel)
The RapidPath plugin controls (writes to) some parameters for operation. If you change the value of any of them, your change will be overwritten.
| Parameter |
| CC-01 |
| CC-02 |
| CC-06 |
| CC-07 |
This can be done automatically via Mach.
Go to Configure | Plugins | RapidPath - MachMotion:
Select the Other Devices tab, Click on the Hitachi VFD in the dropdown on the left and then select the Device Parameters at the bottom of the page:
From here you can click the Load from File button. Navigate to the Plugins/Dependencies/RapidPath/DriveConfig/Hitachi_VFD directory and select the file: Hitachi_Install_EtherCAT_I_O_device.drvprm.
Once it has loaded the parameter values, those which were updated, will be highlighted in green:
Click Write Changes button to save the updates to the drive.
You will need to recycle the drive for the change to the fan to take immediate effect.
